IMPROVEMENT lN PLOWS.

Specification forming part of Letters Patent No. 204,902, dated'June 18,1878; application filed December 17, 1877.

To all whom it may concern:

Be it known that I, JOHN LANE, of Chicago, in the county of Cook andState of Illinois, have invented a new and useful Improvement in Plows,which improvement is fully set forth in the following specification andaccompanyin g drawings, in which- Figures 1 and 2 are views of a plowfrom opposite sides, showing my improvement attached. Figs. 3 and 4 areviews of my improvement detached from the plow.

My invention relates to steel plows; and consists in providing apeculiarly-constructed frame, which I call a frog, and to which theseveral parts-4. 0., share, share end, land-side bar, standard, andmold-board-are bolted, and by which the point of the share is supported,as hereinafter shown.

The object of my invention is to provide a frog or frame on which allthe parts are combined and bolted, and which gives support to all ofthem, and especially gives support to the point of the share Without anyadditional lugs, ears, or bars, and makes a strong, cheap, andattractive plow,

In the drawings, A is a flange, extending from under the share to thestandard, and conforming to the curvature of the mold-board, whichflange is bolted to the share at c and to the mold-board at d and e.

B is a turn-down support, extending along by the side of the land-sidebar and forward by the side of the turn-down end of the share and underthe share, giving support to the point of the share, and to which theland-side bar is bolted at b and the share end at a.

O is a twisted ear, fitting the side of the standard E, and to which itis bolted at f.

The flange A does not extend forward with the support B, but springs outfrom the top of the support B back of the perforation a, as shown in thedrawings. This is to provide that the perforation a may be high up, aswhen it is low down the nut on the bolt in the perforation a is liableto gather trash and roots, causing the plow to clog and work had, while,when made as shown, the perforation a is high up, with nothing betweenthe nut and the share above it,

That portion of the flange A between the perforations c and d is wide,extending under and supporting the share and mold-board where they meetin line together. Above the perforation d the flange A reduces to a merebar, with an enlargement at the perforation e,

as shown in the drawings, making a flange of light weight and greatstrength.

The support B, the flange A springing therefrom, as shown, the ear 0,and the perforations a, b, c, d, e, and f are all so arranged that noother bars, ears, lugs, or perforations are required to combine togetherand support the several parts of the plow, as shown, and the land-sidebar, standard, and mold-board may be of the most simple construction,without lugs, ears, or supports, my improved frame or frog giving acomplete and sole support in uniting all the parts together andsupporting the point of the share, as shown in Figs. 1 and 2, in which Dis the land-side bar, E is the standard, F is the mold-board, G is theshare, and H is the turn-down share end.

My improved frog may be made of either cast or wrought metal. I preferto make it of cast-steel, whereby it may be light and strong.

I am aware that frames and blocks on which some parts have been boltedhave been before used, and I do not claim, broadly, a plow-frame.

What I claim as new, and desire to secure by Letters Patent, is-

The plow-frog frame formed of one piece of metal, consisting of thesupport B, having the flange A springing therefrom behind theperforation a, leaving the support B extending forward alone to supportthe point, and with; the ear 0 and the perforations a b 0 cl e f, asshown, by which the land-side bar D, standard E, mold-board F, share G,and share turndown H are attached, and whereby the perforation a maybehigh up near the share,'all constructed substantially as shown, andfor the purpose set forth.

JOHN LANE.
